Handles 29and 30, respectively, are provided on top and on the rear wall of thereceptacle for moving the latter into and out of engagement with thelugs 26 and for carrying the receptacle While it is removed from theboiler.

In practice, a suitable hook or poker 3| may be inserted through thetending opening 32 in the front wall of the boiler and moved from fullline to dotted line positions illustrated in Figure 3 to transferclinkers from the fire bed in the fire box 2 4 through the openings 22and 2! into the receptacle 2B. The receptacle 28 may then be tiltedslightly to be removed from the boiler and may then serve as a scuttleto carry the clinkers from the boiler room. Any suitable cover (notshown) or another receptacle like 20 may be used to close the opening 22in the boiler while the first mentioned receptacle is detached.

Thus, the construction not only eliminates the objections mentionedabove but also obviates the necessity of removing clinkers from astorage space or chamber to a portable receptacle. The receptacle illitself is portable yet is mounted on the boiler A in such a way thatgases and heat from clinkers in the receptacle will pass through theregistering openings 2i and 22 into the combustion chamber 33 of theboiler. Consequently, there is no heat loss or fire hazard, etc., asheretofore.

Preferably the clinker chamber l and the receptacle 20 are opposite thetending openings 3 and 32, respectively, but obviously such chamber andreceptacle may be located elsewhere relative to such tending openings,as long as they are in position to receive clinkers from the fire bedand may be reached from the tending openings by a suitable implement. Itshould also be noted that in Figures 1 and 2 the partition extends tothe bottom 13 of the boiler and that in Figure 3 the receptacle 2!! ismounted opposite and in substantially a horizontal plane with the firebox 24 of the boiler, hence in each instance the clinkers are receivedin chambers or receptacles separate from and independent of the stokerspaces i l and 3 3, respectively, of the boilers. Any suitable means(not shown) may be employed as outlets for ashes from such boilers.

In Figure 6 I have shown another modification wherein the partition orbridge wall 4!] is adjacent the front Wall 4! of the boiler, while theoutlet 42 for the stoker 43 is substantially midway between saidpartition 46 and the rear wall M of the boiler. In this construction thestoker 23 extends through a suitable opening in a side wall of theboiler, and the clinkers are adapted to be removed from the clinkerchamber 45 through opening 46 in the front wall 4| of the boiler. Anysuitable door such as 41 may be used to normally close the opening 45.Thus, with the construction just described, the partition 40 is highenough to retain fuel on the stoker side thereof but is low enough topermit clinkers to be dropped over it into the storage space or chamber45. In practice a suitable hook or poker such as 48 may be insertedthrough the tending opening 49 in the front wall of the boiler and movedupwardly and forwardly from the full line to the dotted line positionsillustrated in Figure 6 to transfer clinkers from the fire bed in thefire box 50 to the storage chamber 45. Thus, only one door such as 41 isrequired at the bottom of the boiler.

What I claim as my invention is:

1. A heating plant having a fire box and a combustion chamber arrangedin superposed relation and an outer casing for said fire box andcombustion chamber, one upright wall of said casing being providedadjacent the upper end of the fire box with a clinker opening, anotherupright wall of said casing being provided adjacent the lower end of thecombustion chamber with a tending opening through which a suitable toolmay be inserted to move clinkers from the fire box through the clinkeropening, the upright walls aforesaid being in opposed substantiallyparallel relation to each other, the openings in said opposed uprightwalls being substantially in horizontal alignment, and a removableclinker receptacle mounted upon the outside of the first mentioned wallfor receiving and containing clinkers discharged through said clinkeropening.

2. A heating plant having a combustion chamber, a fire box below andopening upwardly into said combustion chamber, and an outer casing forsaid fire box and combustion chamber, the rear upright wall of saidcasing being provided adjacent the upper end of the fire box with aclinker opening, the front upright Wall of said casing being providedadjacent the lower end of the combustion chamber with a tending openingthrough which a suitable tool may be inserted to move clinkers from thefire box through the clinker opening, a clinker receptacle upon theoutside of the first mentioned wall for receiving and containingclinkers discharged through said clinker opening, and a mounting forsaid receptacle permitting quick separation of the receptacle from saidcasing and access to said clinker opening.
